.FABBRIOA ITALIANA AUTOMOBILI TORI ITALY.

NO,- OF TURIN, ITALY, A CORPORATION OF COMB USTION-MOTOB To all whom it may concern:

Be it known that I, GIOVANNI ENRICO, engineer, a subject of the King of Italy, residing at Corso Dante 3537, Turin, Italy, have invented certain new and useful Improvements in Combustion-Motors, of which the following is a full, clear, and exact specification.

The objects of the present invention are for commanding the admission and discharge of-gases in combustion motors in a simple and efficient manner.

The invention is illustrated in the annexed drawings wherein- Figure 1 shows a longitudinal section of an ordinary motor embodying the features of the invention and Fig. 2 shows the same .on an enlarged scale. a

d, c, are the admission and discharge valves respectively located at the top of the cyline der, and bearing against their seats by the action of a bow s ring m fixed to column a carried by the cyhnder. Upon the standard 1' fixed to the cylinder is pivoted an oscillating beam b whose ends are flush with the heads 0, (1, so that the latter bear against their seats when the oscillating beam is in its middle position. I

To one end of the oscillating beam 6 is pivotally connected a stem p guided in corresponding holes and acted upon by a spring m so that its lower end is pressedto bear against the profile of a cam f. The cam carried by the revolving stem has a pro e designed in such a manner t lat during the compression and combustion period the stem bears against a segment of a circle a, b so t at the oscillating beam can rest in its middle position. During the period of discharge 6 c the cam shows a rise or a profile of a larger radius so as to push the stem 11 causing an oscillation of the oscillating beam 12' so as to Specification of Letters Patent.-

Application filed March 1a, 1906. Serial No; 305,814.

Patented Aug. 3, I90" open the discharge valve 0.- During the pe- 10d'OfiIltIOdU0t10I1 or aspiration a fall, or a segment of a smaller radius 0, 0/ comes in contact with the stem p and, under the action of spring m which is stronger than the spring m, the stem p causes the oscillating beam 1) 'to oscillate toward the stem of the aspiration valve d which leaves its seat and al ows the gases to be admitted. It will thus be seen in the construction shown that the cam has an intermediate face or dwell, a rise adapted to operate one valve, and a fall adapted to operate the other valve, and that a single rod 1; transmits these movements to both valves;

While I have shown and described one construction of my invention, I do not wish to 'be limited thereto since the construction may be considerably modified without departing from the invention.

What I claim is: v

1. In a combustion motor, an admission valve, a discharge valve, a bow spring tending to seat both said valves, an oscillating beam adapted to bear against the stems of said valves, and a single cam foroperating said beam.

2. In a combustion motor, an admission valve, a discharge valve, a bow spring m for said valves, an oscillating beam 1) adapted to bear against the stemsof said valves, a cam f operating said beam through a rod p, and a spring'm of greater strength than spring m for moving said rod p. y

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
